The redevelopment area and usage is essentially the same as we previously reviewed in October of 2006. At that time we estimated that the fully developed average day demand would be approximately 120,000 gallons per day and the maximum day demand would be approximately 250,000 gallons per day. These estimates were based on experienced residential demands in the metropoiitan area for the apartment and townhouse areas, and from general published data for retail areas. It was assumed that the retail area would include a reasonable percentage of restaurant area which it the most intensive water use land use type ex ected within this retail area. These assumptions translated to an overall water use of approximately 3,200 gallons per gross acre per day. We feel that the numbers above are conservative. The current deveiopment plan includes 4°� more residential development and 6% less Retail/Office development than was listed in the October Land Use Plan, so we feel that the previously developed numbers are still accurate. The analysis portion of this mema consisted of updating the hydraulic model of the Centerville water system that was prepared during the report phase for the 0.5 MG elevated tank that was completed in 2003. The tank itself was completed in 2005. The hydraulic model was updated to match the 2006 Maximum Day Demand of 848,000 gallons. The model was also updated to include the new 0.5 Mg Elevated Tank and to reflect the fact that the existing 100,000 gallon tank was removed. In addition, all of the mains that have been constructed since the 2003 hydraulic model was prepared were added to the model. This updated hydraulic model was then used to evaluate the ability of the Centerville Water System to provide service to the fully developed downtown redevelopment. With the construction of the 0,5 MG elevated ta�1k, and with planned construction of a third well as outlined in the feasibility report for the elevated tank, it is anticipated that the tenterville water
