Flowing hydrant is assumed to be on a circulating main or downstream of the pressure test hydrant on a dead -end system. 2. Flow analysis assumes a gravity flow system with no distribution pumps and having no demand, other than the test flow. 3. The distance between hydrants, elevations & main diameters are for information only.

City of College Station Public Works Department 1101 Texas Avenue College Station, Texas 77840 Re: Fire Flow Review Chick -fil -A — Case File x`11-00500031 College Station, Texas Dear Mr. Norton: Project No.: R0100722- 50004.32 With this letter we hereby provide notification that the fire flow to the proposed Chick -fil -A restaurant will meet the demand of the building. The following information was used in our evaluation: • Tables B105.1 and C105.1 of the 2009 IFC, Type VB — Wood Framed Construction with Brick Veneer, 4,596 SF building requires a hydrant fire flow of 1,750 GPM at 20 psi • Fire sprinkler system will be provided which allows for a 50% reduction of the required fire flow but no less than 1,500 GPM o Fire flow test performed by College Station Utilities on March 9, 2011 (refer to the attached flow test) • Fire Flow Summary Report prepared by Strong Systems International, Inc. (refer to the attached test report) The City of College Station Utilities provided the fire flow test to our office dated March 9, 2011, which was coordinated with the fire sprinkler designer, Strong Systems International, Inc. Using the flow and pressures provided, the flow at 20 psi will be 16,818.5 GPM, well above the required fire flow. Please note that this evaluation is good as of the date of this letter and does not warrant the fire flow to the restaurant if improvements are made to the public water line system.
