if needed. At this stage the City will identifY any intended model "operator", so that person can participate in the model design and development, become familiar with the model approach and structure, and help assure successful model training and transfer to the City. 1.5.3 Design City models for ease of use and updating structuring it around a series of logical tables that build underlying information into utility financial summaries. Furthermore the Consultant will design this table structure for printing, reporting, and communicating the model information to both technical users and decision-makers. 1.5.4 Link planning information, physical engineering capacity and efficiency data, management and administrative data, and financial information into a comprehensive picture of future utility options and their financial consequences to the City. When variables change, such as more rapid growth and the need for capital improvements, the City's model will simulate the effects of the capital program on system capacity and efficiencies, capital and operating costs, and needed revenue requirements. The Consultant will also use the model to assess the potential costs (or avoided costs) and effects of external variables or non-structural management programs such as anticipated weather conditions or enhanced conservation affecting water sales, improved billing collections, shaving the "peak" programs, or other such initiatives. 1.5.5 Utilize the IPFM to assess the financial effects of alternative capital programs by including a "wish list" CIP for which particular pf(~iects may be turned on or off in the IPFM, the prqiect costs or date of funding changed, cash versus debt fmancing evaluated, and any known physical effects of the prqiect to be incorporated in the model forecast (e.g. change in supply, reduction of unaccounted-for or III, change in pumping efficiencies, peak capacity factors, etc.). 1.5.6 Design models around the City's budget template with sufficient accounting detail and user- specified controls to be very useful in generating the first several versions of the annual departmental budget. This budget template will also acknowledges the fund structures related to utility finance in terms of operating versus special capital or other funds. 1.6 TASK 5 - GROWTH AND SERVICE DEMAND FORECASTS The Consultant will: 1.6.1 Work closely with City staff to identifY or develop the most appropriate population and economic forecasts that will drive the projection of utility growth over the planning period. 1.6.2 Make separate accounting of water and wastewater customers in the model structure, and any particular issues affecting the growth or water service versus wastewater service will be considered. Consultant will work with the City or its wholesale customer to identifY potential service demands ITom this source. Trends in per capita water use will also be considered in making the forecast.
