I r assumed the firat 700 teet of pipe to be 8-inch,the next 920 feet to be 18-inch(to drde 2)and tAe � last section of pipa to be 72-Inch(between circles 2 end 1). I abo oommunfcated with Ryan Sess beforo I did the analysis end he tdd me there would be appro�mately 1500 fest o(pips(c the y buildings on phaae II. Forthia phaae II pipinp, i assumsd a 12-inch dismeter main. And ayain, i want to point out that fhe City's water rt�odel uses peak-hour demanda at all nodes. > VYrth water mains of the above specified diameOx,and a 2,000 gpm Ibw to the phate II buildinps, the rosidual hesd at that node would be 550'NAVD datum. Ryan aafd fhet the ebvafbn of that node would be approximaEely 490'NAVD–that gives a residual preseuro of 28 pai. With 1he firo 1bw of 2,000 gpT at circle 1,fhe rosidual head at that node would be 559'NAVD datum. Alao, I was mistaken when I said there was an operating head in tM Gb�wood line of 885. During the peak hour demand, it's actually at 858–I didn't roalize I was bxicdys. So,thero wi�l be very little differenoe in the water pressures at the park H you choose to co�nect them to lhe 657 zone at a later date,as you've proposed. Therefore, in summary, N you would like to consWct a temporary Ge to the G'enwood 1(ne,an 8- inch main would be adequate for the portion of the syetem that is proposed for abandonment. However,there is a bt at the aouth comer of Sievera-Deucy and Gknwood fhat wNl need to be served later–wouk the'temporary"line be an appropriate connectan M fhat lot9 It ft would, it may be best to use a 12-inch main to accommodate later devebpment on the lot. Please let me know if you need eny additional information. Thank yoo. Jane 2irt!mertnan City of Everett ---0riginal Message— From: lNIN�N. ,��,�� S�nt: Wednesday, March 22,200017:14 AM ,. .

Our plan is to wnnect to pressure zone 685 iniHally, lhen construct a loop to pressure zone 657 next year. The drawing has notes fhat, hopelully,show the pla�. If you would, could you detertnine the residual pressure at poinls 1 antl 2 wiMi a fiow of 2,000 gpm. I'm thinking this will be adequate fire flow for fhe ballfielda. �
