I <br /> believe the meter is east of the tracks and that is the point where the 8-inch ductile becomes a private service line. Can <br /> you verify (did Mike left any notes about it?) and make the map change. <br /> Mr. Brooks-And regardless of the ownership of the service—is this private 8-inch line sufficient for the residual fire flow <br /> requirements? If not Utilities is looking at our own improvements from Medora to WMVD.This 6-inch line needs to be <br /> replaced and is on our radar due to its break history and size. Seems to me the optimal approach could be upgrading <br /> the line from Medora and also adding another service line from WMVD into this area—any way we can work this out? <br /> And since the private system is not separated between hydrants and their service line, the appropriate backflow devise <br /> (double check min) must be included on all connections to us. <br /> Thanks <br /> From: Tim Markham <br /> Sent: Tuesday, November 01, 2016 10:11 AM <br /> To: Mark Sadler <br /> Subject: FW: Sprinkler system submittal for 25 E Marine View Dr/ K1610-002 <br /> FYI <br /> Tim Markham CCS <br /> City Of Everett <br /> (425)257-8833 <br /> t m a r k h a m@ eve rettwa.�ov <br /> From: Kirk Brooks <br /> Sent: Tuesday, November O1, 2016 9:08 AM <br /> To: therondC�firesystemswest.com <br /> Cc: Tim Markham; Jim Spooner; Jim Venturo; Paul McKee; Meg Haley <br /> Subject: Sprinkler system submittal for 25 E Marine View Dr/ K1610-002 <br /> Theron, <br /> A review of your submittal and our records indicated that there is no backflow prevention installed for this system <br /> (Building protection and hydrant system). After a review with our backflow specialist and water department <br /> superintendent it becomes apparent that we take this opportunity to address this issue.The water department staff has <br /> done a field review of what they consider the best location for the vault to house the devise. I have attached a drawing <br /> indicating the location and a standard detail of the assembly.The backflow devise will be a condition of the sprinkler <br /> permit but the work can be done concurrentiy with final inspection approval of the system dependent on the backflow <br /> ;--, ' <br /> 1 _% <br />
