Report for Castlegate II Subdivision, Section 105 College Station, Texas July, 2014 Prepared By: •s Schultz Engineering, LLC TBPE Firm Registration No. 12327 2730 Longmire, Suite A College Station, Texas 77845 979.764.3900 .'0 Or .�t .,« ....P.. ,....,., ULR ** %#N*k__4P4 0.40bi4*• y. lis4041 ' s s 7 io-r � F-,2327 SCHULTZ ENGINEERING, LLC. General Information Location: The Castlegate II Subdivision, Section 105 is a 8.551-acre residential subdivision being developed immediately northwest of the existing Castlegate II Subdivision, Section 103 in College Station. The Final Plat shows a total of 40 lots in this section. General Note: An analysis was conducted on the entire Castlegate II water system to ensure its ability to serve all lots under fully developed conditions. This analysis was conducted with water line sizes of 8"or less to demonstrate that larger size lines are not necessary even though they may be required by the City for future development in the area. Refer to the report by Phillips Engineering titled " Water System Report For Castlegate II, Section 200 College Station, Texas",revised April 2011. Primary Water Supply: Castlegate water service is provided by an existing 8" line on Victoria Avenue and an 8" line that lies in an easement in Section 7 of Castlegate. Section 200 was connected to each of these lines, and both lines will be used to provide looping in all future phases of the development. Section 105 connects to an existing 8" waterline that was constructed with Castlegate II Section 103 and existing 6" waterlines constructed with Castlegate II Section 101. Land Use: Single family residential Design Criteria/Analysis Primary Water Supply: Existing 6" water line along Kimbolton Drive, an existing 6" water line along Warkworth Lane and an existing 8" water line along Etonbury Lane. Existing System Pressure Tests: Flow Hydrant-See Exhibit B Flowrate: 1,530 gpm Static Pressure: 90 psi Residual Pressure: 88 psi Exhibits: Exhibit A—Water Layout Exhibit B—College Station Utilities Flow Test Report Exhibit C—Analysis Summary Fire Flow: 1,000 gpm for Single Family Residential Domestic Use 1.5 gpm per lot for Single Family Residential Section 105— 40 Lots=60 gpm Development Under Construction(Section 104)— 44 Lots= 66 gpm Development Under Construction(Section 103)— 39 Lots=58.5 gpm Development Under Construction(Section 102)— 26 Lots=39 gpm Development Under Construction(Section 101)— 42 Lots=63 gpm Existing Development(Section 100)—42 lots=61.5 gpm Future Development(Section 106)— 44 Lots= 66 gpm Future Development(Section 107)— 41 Lots= 61.5 gpm Total Domestic Demand=475.5 gpm The proposed 8"& 6"water lines are in accordance with the BCS Water Design Guidelines. This report provides the results of the water system analysis under the fire flow and domestic demand requirements, (1475.5 gpm)which produced the lowest pressure in the system. Water System Summary of Section 104 Summary of Calculations w/Minimum Required Line Sizes Domestic Demand Pressure Min. 76.7 psi Velocity Max. 3.04 fps Pressure Min. 68.7 psi Fire Flow Demand FH 10 Velocity Max. 11.72 fps Pressure Min. 68.9 psi Fire Flow Demand FH 11 Velocity Max. 9.43 fps Pressure Min. 68.8 psi Fire Flow Demand FH 12 Velocity Max. 11.72 fps Pressure Min. 6.89 psi Fire Flow Demand FH 13 Velocity Max. I 9.43 fps As shown above the system exceeds the minimum required pressures of 35 psi for domestic flow and 20 psi for fire flow in both analyses. The maximum velocity of 11.72 fps is less than the required maximum of 12 fps. Conclusion The proposed 8" and 6" water lines meet or exceed all of the design criteria for the City of College Station. They will provide adequate water pressure, flowrate and velocity for both domestic and fire flow demands.

Future Development(Section 107)— 41 Lots=61.5 gpm Total Domestic Demand=475.5 gpm The proposed 8"& 6"water lines are in accordance with the BCS Water Design Guidelines. This report provides the results of the water system analysis under the fire flow and domestic demand requirements,(1475.5 gpm)which produced the lowest pressure in the system. Water System Summary of Section 105 Summary of Calculations w/Minimum Required Line Sizes Pressure Min. 76.7 psi Domestic Demand Velocity Max. 3.04 fps Pressure Min. 68.7 psi Fire Flow Demand FH 10 Velocity Max. 11.72 fps Pressure Min. 68.9 psi Fire Flow Demand FH 11 Velocity Max. 9.43 fps Pressure Min. 68.8 psi Fire Flow Demand FH 12 Velocity Max. 11.72 fps Pressure Min. 68.9 psi Fire Flow Demand FH 13 Velocity Max. 9.43 fps As shown above the system exceeds the minimum required pressures of 35 psi for domestic flow and 20 psi for fire flow in both analyses. The maximum velocity of 11.72 fps is less than the required maximum of 12 fps. Conclusion The proposed 8" and 6" water lines meet or exceed all of the design criteria for the City of College Station. They will provide adequate water pressure, flowrate and velocity for both domestic and fire flow demands.
