Box 9960 1008 Woodcreek Drive, Suite 103 •College Station, Texas 77845 (979) 693-3838 • Fax: (979) 693-2554 • Email: McClureBrowne@Verizon.net College Station, Texas 77842 Re.: Fire Flow Letter Adamson Lagoon Building MBESI No. 10140005 Dear Erika: This letter shall serve as our fire flow analysis of the proposed improvements for the above referenced project. This project consists of the replacement of the existing ±2,300 s.f. pool building with a new 3,958 s.f. pool building. The proposed building will be Type 1118 construction and will not be sprinklered. Based on Table 8105.1 of the International Fire Code, the minimum fire flow requirements for this building will be 1,500 g.p.m. Therefore, a new fire hydrant will be installed approximately 62' northeast of the proposed building to meet the fire flow requirements. If you have any questions or need any additional information, please do not hesitate to call. Sincerely, !!: J. Dale Browne, Jr, P.E • l ..
