RE: HYDRANT FLOW TEST
Project No. 98705
Dear Fred:
The public water supplies serving the project site were conducted on October 7, 1998, and determined to be
more than adequate to meet the minimum fire flow requirements of Tualatin Valley Fire & Rescue. Test results
should be representative of water supplies available to the project site at all times of normal water system
operation.
Available fire flow is estimated to be 6,028GPM at a residual pressure of 20 PSIG. Required fire flow is
calculated to be I ,738GPM.
Static Pressure= 79 PSIG
Residual Pressure= 68 PSIG
Corrected Flow= 2434 GPM
The flow hydrant was located on Southwest Upper Boones Ferry Road approximately 100 feet north of
Southwest 72nd near the railroad tracks. The pressure hydrant was located on Southwest Upper Boones Ferry
Road in front of Burgerville.
If you have any questions, please contact this office.
Sincerely,

• B) MULTIPLE OCCUPANCY HAZARD
Use the following when a single fire flow area contains multiple occupancy hazards. Each occupancy
. will be broken down as a percent of the total fire floor area they occupy. The fire flow for each •
occupancy will be calculated by multiplying the occupancy factor, fire flow and the percent of the area
that the occupancy occupies. Add the fire flow of all occupancies together to obtain the required fire
flow for the building.
