The fire flow information is as follows : Static Pressure= 96 psi Residual Pressure = 90 psi Flow = 1250 gpm We have not received the fire demand information for the proposed sorority house. They are still working on those values and we will submit them with the next submittal of plans incorporating the city review comments on this submittal. Please contact us if you have any questions or if we can be of further G assistance. Sincerely, GESSNER ENGINEERING Melissa P.

The table, on page nine of the Site Design r.o. Box 10763. 77842-0763 Standards for the City of College Station, states a minimum of one hydrant is required for flows within 1,750 gpm or less. Therefore, the fire hydrant at 1501 Athens should be adequate for the use of Zeta Tau Alpha Sorority. 979.680.8840 FAX 979.680.884 1 2204 S.

The typical wood framed structure supported on a slab-on- grade with drilled piers foundation will have approximately 20,525 square feet. The proposed sorority house will have a sprinkler system built in. With the proposed construction type and square footage, Table B 105.1 found in the appendix B of the International Fire Code estimates the fire flow to be 1,500 gallons per minute. Table C 105.1 of the International Fire Code states this type of flow requires one (1) fire hydrant. The fire flow test information provided to Gessner Engineering in regards to the fire hydrant located at 1501 Athens, at the southeast corner of the property is as follows: Static Pressure = 96 psi Residual Pressure = 90 psi Flow = 1250 gpm The fire flow information for the fire hydrant on Munson was not available. However, since this building will contain a sprinkler system it provides fifty percent credit toward the required flow, therefore , the required flow is 750 gallons per minute. Considering the proposed house will be located between each fire hydrant, the proposed Zeta Tau Alpha Sorority House should have more than adequate fire flow provided.

Bridges: Based on the descriptions provided in the International Building Code, the proposed Zeta Tau Alpha Sorority House will be constructed as a Type VA structural frame. The typical wood framed structure supported on a slab-on- grade with drilled piers foundation will have approximately 20,525 square feet. The proposed sorority house will have a sprinkler system bu ilt in. With the proposed construction type and square footage, Table B 105.1 found in the appendix B of the International Fire Code estimates the fire flow to be 3,750 gallons per minute. Table C 105.1 of the International Fire Code states this type of flow requires four (4) fire hydrants. The fire flow test information provided to Gessner Engineering in regards to the fire hydrants adjacent to the proposed Zeta Tau Alpha Sorority House can be found in the table below, Table One. The fire hydrants are located at 1501 Athens, at the southeast corner of the property, and 1000 Bayou Woods, across Munson on the northeast section of the property.
