term modeling scenario to the year 2020. Demands will be increased based on the 2013 <br />Plan using a single multiplication factor across all model nodes. It is anticipated that <br />supply levels will also need to be increased to match the demand. <br />o Level of Service. Evaluate ability for leased Highline storage to meet designated uses for <br />the short-term (2020) and long-term (2035) planning horizon. Evaluate Peak Hour <br />Demand (PHD) and Maximum Day Demand (MDD) plus Fire Flow using the criteria <br />identified in the 2013 Water System Plan. Identify any conveyance improvements need <br />to use the leased storage. Recommend piping improvements for any new deficiencies <br />caused by the removal of a City owned reservoir. Prepare AACE Class V costs for the <br />updated intertie and any new distribution system improvements. <br />o Compare Alternatives. Compare hydraulic modeling results for the 2013 Water System <br />Plan, 2014 Reservoir Siting Analysis, and the leased Highline Reservoir scenarios. <br />Prepare charts and tables to summarize differences in levels of service and costs. It is <br />anticipated that Highline will provide the cost of the leased storage and any related <br />improvements in Highline's system. Select a preferred Alternative for City <br />implementation. <br />o Meeting No. 2 Preferred Alternative. Review level of service and comparison of <br />alternatives with City staff. Select a preferred Alternative. <br />4. Technical Memorandum No. 1. Prepare a short Technical Memorandum (TM) documenting the <br />study tasks. It is anticipated that the TM will be included as part of a DOH Project Report for the <br />preferred alternative. <br />5. Project Management. Direct all activities within the study as assigned by the City and maintain <br />the project within the contracted scope, schedule, and budget. This includes project <br />administration, monthly invoicing, client and team coordination and quality assurance/quality <br />control review.
