As previously discussed I �a <br /> forwarding, herein, calculations of the estimated fire flow demand for <br /> both the inmediate and future site develognents. These calculations, �� <br /> along with a site layout plan of the fir.e system, are submitte� for your <br /> review and approval. <br /> In stmmiary, Phase I fire demand for the Administration, Operations, and <br /> Maintenance Buildings is estimated to be 2100 ggn, 2500 gpm, and Z000 gpm, <br /> respectively. Phase II demand, also per ISO guidelines, is 2300 gFm, 300C <br /> gpm, ar.d 2750 gpm, respectively. In both cases, the operations building <br /> requires the most protection becaase of the wood frame construction and <br /> lack of sprinklers. <br /> With assistance from the City of Everett, rre determined from their com- <br /> puter water model tnat our proposed looped water system could deliver 2750 <br /> gpm with a residual pressure o[ 22 psi. This should be a�'�quate for our <br /> purposes. <br /> If you should have any questions, please give me a call. I can be reac}ied <br /> at 447-5354. <br /> Sincerely, <br /> , CHIN�MAYO -INC. <br /> � /Pl�/l� � , t, `• <br /> Dou� D.
