Received t-28-20tg as an email 4.31 PM <br />Jerry, <br />Based on the information that you have provided me I have estimated that the minimum fire flow <br />would be: <br />Residential Townhouses 3501 sq feet and greater with automatic sprinklers = L hour flow duration and <br />1000 Gallons Per Minute. This is considering a Type V wood-frame construction. <br />The larger RV storage appears to be a Type lllA ordinary construction - 20,000 sq ft = 2000 x 0.25 <br />(Sprinklers) = 500. (Cannot reduce less than 1000 GPM per IFC). The fire flow would be 1000 GPM for <br />2 hour flow duration. <br />1000 GPM flow rate for 2 hours or 120,000 total water needed for fire suppression. <br />ln reference to your hydrant questions, IFC 507.5.1 allows maximum spacing of 600 feet for the <br />hydrants, since the buildings will be sprinkled. The RV storage building should have a hydrant within 600 <br />feet of it. <br />Thanks, <br />Patrick Nicholson <br />Fire Marshal <br />Kittitas County <br />41-1 N Ruby ST, Suite 2 <br />Ellensburg WA 98926 <br />(sos)8es-3ssa (Cell) <br />(s0e)952-7000 (office) <br />pat. n icholson (@co. kittitas.wa. us
