RE: Water Analysis and Report
Oxford Court Office Building
Lot 4 Block 11 , Castlerock Subdivision, Ph 1 B
College Station, Texas
Dear Alan:
The Oxford Court Office Building is planned for Lot 4, Block 11 of the
Castlerock Subdivision, Ph 1 B. When that subdivision was developed, the water system
was analyzed to determine if sufficient water fiow and ressure was available for fire
demands on these commercial lots. co y of that water re ort is attach The fire flow
used in that analysis was 2500 gpm at the hydrant across the entry driveway from this lot.
The Oxford Court Office Building will lfave 4200 square feet of enclosed area.
We do not yet know the building type that would allow us to determine the actual fire
flow rate required by the International Fire Code. However, if we assume the most
conservative figure using a Building Type V-B1 a building of this size would require
1750 gpm and one hydrant (International Fire Code Tables Bl 05. I and Cl 05.1). Since
our system was analyzed using a fire flow rate of 2500 gpm, we conclude that the water
system is easily capable of serving this building. No additional water report will be
submitted for this development.
Sincerely Yours,
/~~
