B. Minimum Number of Fire Hydrants Required
Required Fire Flow 8894 = I 8 (No. of Hydrants Required
C. Reduction of Fire Flow - Reductions are based on the following:
Cl - Reduced by 25% for all Group R Occupancies without fire sprinklers (multiply by .75)
C2 - Reduced by 25% for a NFPA 72 Fire Alarm System (multiply by .75)
C3 - Reduced by 75% for NFPA 13 Automatic Sprinklers (multiply by .25)
D. Required. Fire Flow
D1 - Group R occupancy I No !x I 1 I = I 8894 GPM (Max. 3000 - Min. 1500 gpm) I
D2 - Fire Flow 8894 GPM X I 0. I = I 2223.5 GPM (Max. 3000 - Min. 1500 gpm) I
E. Available Fire Flow to the Building Test Results: I 5,462 I GPM
Manually enter available fire flow here. Please attach documentation of the flow test that was
made. It shall include date, time, location of static /residual and flow hydrants, and the tester's
name, phone number and address.

Remarks:
The mapping, flow or pressure information contained herein reflects conditions on the date
and time of the test. Tualatin Valley Water District makes no representation as to the system's
ability to meet specific fire flow requirements. Future system capability may differ from the
flows reported herein because of subsequent modifications to the district's system and/or
because flow and pressure may vary by time of day and season. Test gage caliibration
information available upon request.
