� Memorandum �" sonestroo <br /> 70: Mark Statz Project: DT Red. Comprehensive Date: 10/2/2007 Z335Highway36W <br /> Infrastructure Plan SL Paul, MN 55113 <br /> From: Mark Rolfs Client: City of tenterville Tel 651-636-4600 <br /> Fa�c651-636•1311 <br /> Re: Downtown Redelvelopment Hydraulics File No: 616-07161 ww�.bonestroo.com <br /> Mark: � � <br /> We have reviewed the proposed Centerville downtown redevelopment with respect to the water <br /> system. <br /> The redevelopment area and usage is essentially the same as we previously reviewed in October of <br /> 2006. At that time we estimated that the fully developed average day demand would be <br /> approximately 120,000 gallons per day and the maximum day demand would be approximately <br /> 250,000 gallons per day. These estimates were based on experienced residential demands in the <br /> metropoiitan area for the apartment and townhouse areas, and from general published data for <br /> retail areas. It was assumed that the retail area would include a reasonable percentage of restaurant <br /> area which it the most intensive water use land use type ex ected within this retail area. These <br /> assumptions translated to an overall water use of approximately 3,200 gallons per gross acre per <br /> day. We feel that the numbers above are conservative. The current deveiopment plan includes 4°� <br /> more residential development and 6% less Retail/Office development than was listed in the October <br /> Land Use Plan, so we feel that the previously developed numbers are still accurate. <br /> The analysis portion of this mema consisted of updating the hydraulic model of the Centerville water <br /> system that was prepared during the report phase for the 0.5 MG elevated tank that was completed <br /> in 2003. The tank itself was completed in 2005. The hydraulic model was updated to match the <br /> 2006 Maximum Day Demand of 848,000 gallons. The model was also updated to include the new <br /> 0.5 Mg Elevated Tank and to reflect the fact that the existing 100,000 gallon tank was removed. In <br /> addition, all of the mains that have been constructed since the 2003 hydraulic model was prepared <br /> were added to the model. This updated hydraulic model was then used to evaluate the ability of the <br /> Centerville Water System to provide service to the fully developed downtown redevelopment. <br /> With the construction of the 0,5 MG elevated ta�1k, and with planned construction of a third well as <br /> outlined in the feasibility report for the elevated tank, it is anticipated that the tenterville water <br />
