SUBJECT: Fire-Flow Capability for the Proposed
Condominiums on the SE Corner of Benson Road
and I-405
Dear Mr. 01sen;
The capability of the City of Renton's water system has been analyzed for
the purpose of determin4.ng the available water supply for righting a fire
it the proposed condominium development on the SE corner of Benson Road and
1-405. The determination of fire-flow capability was based on the water
system experiencing a maximum day demand, in accordance with the Insurance
Services Office (IS0) criteria, which is used by the Washingtc Survey
and Rating Bureau, the local rating company.
However, the criterion that the largest s*Ingle source of supply is out of
servii.e, due to failure, maintenance, contamination, etc. , was not used.
The largest source of supply to this area is the City's Talbot Hill booster
pump station. Further, it was assumed that the Rolling Hills reservoir
was in operation with a draw-down of approximately 5 feet.
Results of the analysis indicate that the available fire-flow capacity at
the proposed development will be in excess of 2,500 gpm. This conclusion
is supported by the results of the fire-flow analysis for the Country Hills
Condominium Development which resulted in a fire-flow capacity of 3,600
gpm.

Please contact me if you hive any questions or concerns regarding this
analysis.
Sincerely,
